Abstract

Des données en valeurs de gris en trois dimensions (3D) fournies par l'imagerie par résonance magnétique ou la tomodensitométrie sont segmentées de manière binaire avec des variantes d'algorithmes adaptés à l'imagerie médicale et à l'imagerie en général. Les géométries de vaisseaux en 3D obtenues sont utilisées pour une simulation numérique à résolution de leur écoulement sur des grilles de calcul cubiques avec des résolveurs de flux selon la méthode Boltzmann en réseau. Les conditions secondaires nécessaires sont extraites de banques de données ou de mesures non invasives individuelles. Lorsque la dynamique de paroi est importante, elle est simulée en même temps. Les implants, l'angioplastie, les plaques présents dans le patient etc. sont identifiés et introduits dans la géométrie de simulation. De même, des modifications virtuelles (pas encore présentes chez le patient) de géométrie, par ex. des implants à poser, des parties de vaisseau à enlever etc. sont ajoutés à la description géométrique à calculer pour permettre, lors de la planification médicale d'opérations chirurgicales correspondantes, une évaluation préalable précise des effets desdites opérations. Les implants dont la structure fine ne peut être résolue sur la grille de calcul de la simulation de flux sont modélisés sous forme de corps poreux élastiques.
